Introduction

Circuit Breakers are essential safety components in any electrical distribution system. T11-0-20.0A-34481-2-V Circuit Breakers are widely used in commercial and residential applications. This article will provide an in-depth discussion of the application field and working principle of T11-0-20.0A-34481-2-V Circuit Breakers.

T11-0-20.0A-34481-2-V Application field

T11-0-20.0A-34481-2-V Circuit Breakers are specifically designed for electrical overload and short circuit protection. They are primarily used in high-power circuits such as those found in industrial and commercial buildings. They can also be used to protect residential wiring systems, motor circuit protection and overhead transformer protection. These circuit breakers are also used in combination with other protective devices such as fused switches and contactors.

T11-0-20.0A-34481-2-V Circuit Breakers are designed for use with AC frequency of 50 Hz/60 Hz and operating voltage up to 690 V. They are designed for short circuit withstand of up to 20 kA. They are available in several different frame sizes and current ratings, ranging from 15 A to 3000 A. They are certified for use in industrial applications and are UL listed.

T11-0-20.0A-34481-2-V Circuit Breakers also provide a high level of operational reliability. They feature a built-in thermal-magnetic trip unit, allowing the trip unit to adjust the operating characteristics based on changes in ambient temperature. This allows them to provide a shorter trip time during high temperature conditions. This feature is particularly beneficial when operating in high-temperature environments. These circuit breakers also feature a trip-free mechanism, which ensures that the circuit breaker will trip even if the faulted circuit is not disconnected, saving time and money.

Working Principle

The working principle of T11-0-20.0A-34481-2-V Circuit Breakers is based on a thermal-magnetic trip unit. This trip unit consists of a bimetallic strip that is connected to a solenoid. When the current in the circuit exceeds the rated value of the circuit breaker, the heat generated by the current causes the bimetallic strip to bend. This causes the solenoid to be pulled, breaking the connection between the circuit breaker and the main power source.

In addition to the thermal-magnetic trip unit, some T11-0-20.0A-34481-2-V Circuit Breakers also feature a current transformer. This current transformer is connected to the circuit breaker and can detect when the current in the circuit exceeds the rated value. If the current exceeds the rated value, the current transformer will send a signal to the trip unit, activating it and disconnecting the circuit.

Conclusion

In conclusion, T11-0-20.0A-34481-2-V Circuit Breakers are specifically designed to protect electrical systems from overload and short circuit protection. They are used in a wide range of applications, from industrial and commercial to residential and motor circuit protection. These circuit breakers feature a thermal-magnetic trip unit and a current transformer to provide a fast and reliable trip time. They are UL listed and certified for industrial use.
